OK,  checked with a nightly past the 9 July build. Not affecting Vulkan
rendering with a recent nVidia GPU and drivers. So not a general issue.

RenderMethod: vulkan
Vendor: 0x10de
Device: 0x2803
API: 1.4.303
Driver: 576.160.0  //LO generates it wrong, should be 576.40.0.0 (bug 160783)
DeviceType: discrete
DeviceName: NVIDIA GeForce RTX 4060 Ti
Denylisted: no

You could try to disable the "Hardware Accelerated GPU Scheduling" (HAGS) that
WDDM 3.2 enables by default. Widows registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers
DWORD (32 bit): 'HwSchMode'  [hex 1 off, hex 2 on]

But don't forget to *turn it back on* if it has no effect. ;-)
